Abstract
【解決手段】 燃料電池用ガス拡散層としてのコレクタ12すなわちメタルラスMRは、第1工程と第2工程を経て成形される。第1工程は、上刃UHがステンレス板Sの板幅方向における第1加工位置にある状態で、ステンレス板Sに略六角形状の貫通孔を、加工ピッチ分だけずれた位置に2回成形する工程である。第2工程は、上刃UHがステンレス板Sの板幅方向における第2加工位置にある状態で、ステンレス板Sに略六角形状の貫通孔を、加工ピッチ分だけずれた位置に2回成形する工程である。この第1工程と第2工程とを交互に繰り返すことにより、均一な形状を有するとともに所定の板厚を有するメタルラスMRを製造することができる。
